I. du Pont de N emours and Company, Wilmington, Del., a corporation of Delaware Continuation of application Ser. No. 541,155, Apr. 8, 1966. This application Dec. 26, 1968. Published June Int. Cl. D04b 1/18 U.S. Cl. 66-169 1 Sheet Drawing. 11 Pages Specification A knit-fabric structure in which a bare elastic yarn and and a first inelastic yarn are knit together in one set of alternating courses and a second inelastic y-arn of about the same denier as the first inelastic yarn is knit alone in the other set of alternating courses. The yarn (or yarns) in one set of alternate courses are plain-knit, and the yarn (or yarns) in the other set of alternate courses are in a knit-and-tuck arrangement. In successive courses containing tuck loops, the tuck loops are in alternate Wales.

Yarn exposed at the surface of the fabric is predominantly inelastic and the appearance and feel of the fabric approximate the appearance and feel of similar fabrics made only of inelastic yarns.

In knitting the structure, feeding of the bare elastic yarn and inelastic yarn which are knit together is controlled so that the elastic yarn is consistently plaited to the same side (preferably outside) of the inelastic yarn. This is accomplished by using a yarn feed finger having two yam-guiding eyelets, and passing the yarn to be plaited to the inside through the eyelet which is closer to the needles.

The structure is useful for ladies sheer, form-fitting elastic stockings. For this purpose, nylon is the preferred inelastic yarn, and spandex is the preferred elastic yarn. Because of the knit-and-tuck arrangement in alternate courses, stockings of this structure exhibit multidirectional stretch, which enhances their form-fitting performance. The structure can also be used in other form-fitting garments, e.g. bathing suits. Where extreme sheerness is not required, covered spandex can also be used.
